Posco pursues ‘direct lithium production' in North America for 1st time
In partnership with Anson Resources, Australia's natural resource developer, Posco will start the construction of a demonstration plant next year in Green River City, Utah. The facility will evaluate whether Posco's Direct Lithium Extraction technology is feasible for large-scale commercial production.
Unlike traditional lithium extraction methods that depend on the natural evaporation of brine in large ponds, DLE is a cost-effective, innovative process designed to selectively extract lithium from low-concentration brine lakes.
The project marks the first time a South Korean company has taken steps toward directly producing lithium in North America. In contrast, Posco's domestic rivals, including LG Chem, have primarily secured supply agreements with US-based lithium producers rather than pursuing local production.
Earlier Monday, the two companies signed a memorandum of understanding under which Anson Resources will provide the raw materials for lithium and the construction site, where it holds mining rights for lithium brine.
While the additional details of the project, including its timeline and investment volume, remain undisclosed, Posco stated: 'By successfully operating the demonstration plant in the US, we aim to commercialize the DLE technology we have developed since 2016.
The company intends to leverage this technology for investment and commercialization of undeveloped lithium brine lakes across North America.'
According to World Population Review, the US ranked third in the world for lithium deposits in 2023, behind Bolivia and Argentina.
This initiative is in line with the company's focus to secure additional lithium resources outside China, which dominates the global lithium hydroxide market, under Posco Holdings CEO Chang In-hwa's '2 Core + New Engine' strategy, referring to focusing on its core steel and battery materials businesses, while also developing new growth engines.
Meanwhile, Posco Holdings has secured an annual production capacity of 68,000 metric tons of lithium hydroxide, enough to manufacture batteries for approximately 1.6 million EVs. This includes 25,000 tons from its brine lithium plant in Argentina and 43,000 tons from its ore lithium plant in the Yulchon Industrial Complex in South Jeolla Province.

Delska's New 10MW Data Center in Latvia Achieves Tier III Design Certification
RIGA, Latvia, Aug. 19, 2025 /PRNewswire/ -- Northern European data center operator Delska's upcoming facility, EU North Riga LV DC1, has been awarded the prestigious Uptime Institute Tier III Design Certification—an important milestone ahead of its planned launch at the end of this year. Once operational, it will be one of the greenest data centers in the Baltic region. The Tier III Design certification ensures the facility meets strict standards for redundancy, safety, and uninterrupted service, guaranteeing 99.982% uptime. "In a world where even a few seconds of downtime can cost thousands, Tier III means our infrastructure stays online—even during planned maintenance," said Delska CEO Andris Gailitis. Addressing power shortages in major European hubs, the 10 MW site, offering up to 250 kW per rack, is built for next-generation workloads, including AI and high-performance computing (HPC). Its modular 6,000 m² layout is fully scalable, with the ability to expand the data center campus site up to 30 MW. Sustainability is at the core of the design. The facility will run entirely on 100% wind energy, with backup generators powered by Neste MY renewable diesel. Targeting a PUE of just 1.3, it will use advanced free-cooling systems, hot-aisle containment, an effective Weiss Technik wall cooling system and Trane Turbocor-based chillers. It supports both air cooling and high-density direct-to-chip cooling. Delska also aims for LEED green building certification, an achievement held by fewer than 15 buildings in Latvia. Upon completion, LV DC1 will undergo Tier III Facility certification to confirm its construction and operations meet the same high standard as its design. This will be Delska's third Tier III-certified data center and sixth overall, joining two Tier III Facility-certified sites in Lithuania. Plans include an additional Lithuanian data center and another facility in the region, strengthening Delska's Baltic data centers' network. About Delska Delska is one of the largest data center operators in the Baltics, with over 26 years in IT and network infrastructure. Operating fully green Tier III and PCI-DSS certified facilities in Riga and Vilnius with 19 MW capacity, Delska also maintains points of presence in Frankfurt, Amsterdam, and Stockholm. Its portfolio includes cloud, server rental, network, security, and managed services. Since being acquired by Quaero European Infrastructure Fund II in 2020, Delska has significantly expanded its infrastructure and improved energy efficiency. In 2024, DEAC (Latvia) and DLC (Lithuania) merged under a new Delska brand, and this year RackRay (Lithuania) joined the group of companies.

Upstage teams up with AWS for global AI expansion
South Korean AI startup Upstage said it is teaming up with Amazon Web Services to expand into Asia-Pacific and US markets, while enhancing its Solar large language model to make high-performance, low-cost generative AI more accessible. Under the agreement, Upstage designated AWS as its preferred cloud provider and will use its infrastructure to build, train and deploy foundation models, the company said. It will leverage AWS' machine learning stack — including Amazon SageMaker as well as Trainium and Inferentia chips — to power Solar, and its AI-based document processing suite, Upstage added. As part of their expanded strategic partnership, Upstage also received a minority equity investment from Amazon, marking the first time the company has attracted direct funding from the US tech giant. The size of the investment was not disclosed. "We are pleased to support the next stage of Upstage's growth as it expands its Solar foundation model and document intelligence solutions," said Abhijeet Muzumdar, vice president of corporate development at Amazon. "By backing visionary companies like Upstage, we aim to foster continued innovation in generative AI." Upstage has long collaborated with AWS, training its Solar model on SageMaker and implementing the proprietary Depth-Up Scaling method on AWS infrastructure to improve performance. Its Solar lineup is currently offered via Amazon Bedrock Marketplace, SageMaker JumpStart and AWS Marketplace, the company explained. "Upstage and AWS have built a strong foundation through years of collaboration, and this agreement marks a new chapter in our shared vision to accelerate global AI innovation," said Upstage CEO Kim Sung-hoon. "Through this strategic partnership, we will expand our reach and deliver safe, intelligent and high-performance AI solutions to more public institutions." The company also said its "AI Initiative," launched in April, is also part of the collaboration with AWS. The program is designed to accelerate the adoption of generative AI by educational institutions and non-profit organizations, with more than 200 institutions, including Seoul National University and Korea Advanced Institute of Science and Technology.

Seoul stocks end lower for 2nd day as cautious investors eye key global events
South Korean stocks closed lower for the second consecutive session Tuesday as investors remained cautious ahead of key global events, including a policy outlook on the US Federal Reserve's potential rate cuts. The Korean won lost ground against the US dollar. The benchmark Korea Composite Stock Price Index lost 25.72 points, or 0.81 percent, to close at 3,151.56. Trade volume was light at 281.47 million shares worth 8.54 trillion won ($6.14 billion), with decliners sharply beating gainers 610 to 270. Foreigners sold a net 453.5 billion won worth of local shares, while individual and institutional investors purchased a net 88.7 billion won and 252.9 billion won, respectively. The index had opened in negative territory and traded within a narrow range during the morning session, but extended losses in the afternoon on heavy foreign selling. Investors remained cautious as attention turned to the Fed's annual symposium later this week, where Fed Chair Jerome Powell is expected to speak on the central bank's policy direction. Also in focus is the upcoming summit among US President Donald Trump, Russian President Vladimir Putin and Ukraine President Volodymyr Zelenskyy, which investors hope may lead to progress toward ending the prolonged Russia-Ukraine war. Lee Kyung-min, an analyst at Daishin Securities, noted that there is heightened global caution ahead of the Jackson Hole meeting, along with growing interest in the potential outcomes of meetings related to the Russia-Ukraine conflict. "With both issues unlikely to produce meaningful results in the short term, and with the absence of other major macroeconomic developments, markets are likely to remain in a wait-and-see mode," he said. In Seoul, market heavyweights closed mixed. Among tech shares, chip giant Samsung Electronics remained unchanged at 70,000 won, while its rival SK hynix retreated 1.68 percent to 263,000 won. Leading battery maker LG Energy Solution went up 0.26 percent to close at 384,000 won. Bio shares were also mixed. Major pharmaceutical firm Samsung Biologics declined 0.39 percent to 1,024,000 won, while Celltrion remained the same at 172,900 won. Defense giant Hanwha Aerospace dropped 6.87 percent to close at 827,000 won. The local currency was quoted at 1,390.7 won against the greenback at 3:30 p.m., down 5.7 won from the previous session.
